Classifying and avoiding singularities in the alternative gravity dark energy models
S. Capozziello, M. De Laurentis, S. Nojiri +1
The future finite-time singularities emerging in alternative gravity dark energy models are classified and studied in Jordan and Einstein frames. It is shown that such singularity…
Modified gravity as realistic candidate for dark energy, inflation and dark matter
Shin'ichi Nojiri, Sergei D. Odintsov
We review the unification of early-time inflation with late-time acceleration in several local modified gravity models which pass Solar System and cosmological tests. It is also de…
Accelerating cosmologies from non-local higher-derivative gravity
Salvatore Capozziello, Emilio Elizalde, Shin'ichi Nojiri +1
We study accelerating cosmological solutions of a general class of non-linear gravities which depend on Gauss-Bonnet and other higher derivative invariants. To achieve this goal a…
Modified f(R) gravity from scalar-tensor theory and inhomogeneous EoS dark energy
Diego Sáez-Gómez
The reconstruction of f(R)-gravity is showed by using an auxiliary scalar field in the context of cosmological evolution, this development provide a way of reconstruct the form of…
gravity constrained by PPN parameters and stochastic background of gravitational waves
S. Capozziello, M. De Laurentis, S. Nojiri +1
We analyze seven different viable -gravities towards the Solar System tests and stochastic gravitational waves background. The aim is to achieve experimental bounds for the t…
Euclidean Methods and the entropy function
Pedro J Silva
We review results of articles hep-th/0607056, hep-th/0610163 and 0704.1405 [hep-th]. Here we focus on establish the connection between the entropy functional formalism of Sen and t…
